Please keep feature requests separate and post them in the Studio One Feature Requests Category.
Please create a new request with Video Thumbnail Tracks as your title.
For your Quantum FP8 Idea, put that FR in General Feature / Product requests.
Please explain (in as much detail with mockups if possible) in your post to get the greatest level of visibility to the developers.
